, To aZ-Z whom "it may concern;

Be it known that I, lRA 'l. GERMAN, a citizen oi the United States, residing at Delmar,

in the county of Sussex, State of Delaware, have invented. certain new and useful Imrovemenis in Music-Leaf Turners; and I do Jere-by declare the followin to be a full, clear, and exact description the invention,

such as will enable ot iersskilled in the art I-ncnt with a sheet'of music, said members be ing each capable of an independent partial rotation upon its axis, to swing its arm from one position to'another, and, in consequence, turn the sheet with which it is connected.

The invention further resides in the particular devices employed for eilecting the rotation of said members, for holding the members against rotation, and for releasing the lastmentioned devices from engagement with said members, to permit their rotation by the firstsnentioned devices.

The invention will be read-i1 understood from a consideration of the ollowin detailed description, and its eferredcm odiment is illustrated in t e accompanying drawings in which like arts or features, as the case ma. be, are esi nated by correspending re .erence nuinera s in the several news.

Of the said drawings :Figure 1 is a fragmental front elevation of a iano equi pod vith the present invention, the music s 'eets wing shown in dotted lines. Fi 2 is a top alan' view of the attachment. ig. '3 is an blarged transverse sectional view of Fig. 1. ig. 4 is a side elevation partly in section. i'g. 5 is an enlarged detail view of one of the peratin levers, the rod .cal'ri'ed thereby, nd the lilock'to which the strip is pivoted. ig. 6 is a side elevation of a modified for-m f the invention. Fig. 7 is a transverse ectional view of Fig. 5. Fig. '8 is an enlorged detail view of one of the rockers shown in h igs. 6 and 7 and the cord fastened thereto.

Referring more particularly to the drawings, 1 designates, generally, the piano,which is of any ordinary type, 2- the key-board, and. 3 the music rack, upon the base 4 of which the leaf-turning attacl'ln'ieut a whole is mounted. Said rack base has formed in its upper face a bearing which receives the lower end of a vertical shaft 5, the other end of whichis fitted in a bearing formed in the laterally bent upper end of a standard], said bent end being fastened to the upper end of a stationary brace 8 whose lower end is likewise fitted in a seat formed in the base 4, to

which latter the foot 9 of the standardalso secured, said brace being located. dire-c .ly in.

the rear of said shaft and between the latter and said standard.

Towards its lower end the shaft is provided with a coil-spring 10 attached at its upper end thereto and at its lower end to the brace, the shaft being further provided adjacent its opposite ends with a pair of laterally-projecting arms 11 and 12, the former of which carries a pair of s ring clips 13, adapted to be engaged with a s act or sheets on the ri hthand side of the open piece of music 14 w ien swung a sufficient distance in that direction, the movement of said arm into such position efiectin a partial rotation of the shaft 5, to which t are arms arerigidly secured, and, in consequence, a tensioning of the spring '10. In order to hold the clip arm in such position and to prevent a backward rotation of the shaft, the lower arm 12, when moved to the right, is adapted to be engaged by a vertical rod 15 whose upper end extends into the path of movement of said arm. Tris rod is carried by a horizontally-disposed lever 16 pivoted at one end between a pair of upstanding ears formed on a block 18 disposed longitudinally of the base plate and secured thereto, the other end of the lever being bent upwardly and provided with a button or head 19 by means of which it is depressed, said lever being normally held in raised position by a coil-spring 2O interposed centrally between the lever and base plate. It will therefore be apparent that. when the lever is depressed, its rod 15 will be released from engagementwith the arm 12 whoreuponthe shaft 5 is free to rotate to the left under the tension of its s ring 10, turning the sheet or sheets to whic-i the-clips 13 are clamped.

, by a spring 20'. theseveral clips 13.

The shaft 5 is further provided witha coilspring 21 which is disposed above the arm 12 and is connected at its lower end to the brace 8 and at its upper end to a hollow tubular member or sleeve 22 fitted loosely upon said shaft and extending tance of the upper end of the latter.

this sleeve is loosely mounted a second Upon sleeve 23 which terminates short of the ends of the first-mentioned sleeve and is connected at its lower end to one end of a coil spring 24 which embraces the projecting lower end .of the first-mentioned sleeve and is likewise fastened at its lower end to the brace. A third sleeve 25 is fitted in liLe manner upon the .second sleeve and likewise terminates short of the ends thereof, being connected at its lower end in a similar manner to one end of a coil-spring 26 disposed upon the projecting lower end of the second sleeve and secured at its other end, to the brace. Each of the sleeves 22, 23, and '25 is likewise rovided at opposite ends with a pair of latera ly-projecting arms 11 and 12 whose arrangement is similar to that of the armsll and 12 carried by the shaft 5, the upper arm 11 of each sleeve being provided with leaf-engaging The lower arm 12 of each sleeve, when moved to the right, is likewise adapted to be engaged by a vertical rod 15' carried by a lever 16, the last-mentioned element being normally held in raised or o erative position eveis being likewise pivoted at their inner ends between pairs of cars formed on the block 18 and having their outer ends provided with buttons 19'.

By reason of the coil-s ring connection between each sleeve and t e braces, it will be ap arent that each sleeve is. capable of an in ependent partial rotation upon its axis,

, the nested arrangement of the sleeves pertial rotation independently of the sleeves, as,

' already described.

In the modified construction shown in Figs. 6 and 7 the base 4 is provided at one or both ends, as preferred, with a series of rockers 27 which correspond to the levers 16 and 16 in the preferred'forn'i, each rocker bein connected by a cord 28, which runs beneat 1 a pulley 29, with the lower end ofa vertical rod 31 which, in like manner corresponds to the rod 15 or 15, as the case may be, the upper endof said. rod being in the. )aths of motion of .the arms 12 and 12. lllach rod 31, which is slidable through a perforated guide 32 secured to the base plate, has fastened thereto a collar 33 against which to within a short dis-' bears the u per end of an expansible coil spring 35, tie tension of said spring ncrmally holding the rod in raised or operative position. The actuation of the rockers will effect the rotation of the shaft and sleeves as in the ireferred form. The numbcn of sleeves utilized maybe greater or less than that shown, the number of levers or rockers varying accordin ly, and numerous other modifications an changes may be made within the scope of the a pended claims, as the invention is not inten ed to be limited to the exact details of construction described and illustrated.
